Below is the Command for Windows,

IT will be almost same in Unix we just need to change the path of Solr lib and class-path separator ; & : Because its java command so should run in Unix also.

java  -Dlog4j.configuration="file:E:/solr-5.5.1/server/scripts/cloud-scripts/log4j.properties" -classpath .;E:/solr-5.5.1/server/solr-webapp/webapp/WEB-INF/lib/*;E:/solr-5.5.1/server/lib/ext/* org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost 192.168.42.13:2787 -confdir E:/New_Solor_Conf -confname Solor_conf

Brief details about command as follows:

Configuration of log4j for logging.

• -Dlog4j.configuration="file:E:/solr-5.5.1/server/scripts/cloud-scripts/log4j.properties

Class path to run "org.apache.solr.cloud.ZkCLI". class.

make sure UNIX and Windows will have different : (Unix seperator) ;(Windows Separator)

• -classpath .;E:/solr-5.5.1/server/solr-webapp/webapp/WEB-INF/lib/;E:/solr-5.5.1/server/lib/ext/
• -zkhost 192.168.42.13:2787 (Remote Host and port where Solr Zookeeper is running)
• -confdir E:/New_Solor_Conf (Local directory what we need to upload.)
• -confname Solor_conf Remote instance name.

If you will not use correct class path you will get error like :

  Error: Could not find or load main class org.apache.solr.cloud.ZkCLI

or

 Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFacto

I am able to upload my local configuration changes without physically login to remote Solr box. Hope it will work for other also.
